NO$X51 - AMT630A Emulator/Debugger
This project started back in 2001, at that time it's been emulating 80C31/80C51/P8xCE558 single-chip 8-bit microcontrollers, which didn't have too much pratical use as it didn't emulate whatever peripherals (like tape decks, washing machines, servo motors, temperature sensors, etc.).
As of 2018 it turned into a fully fledged AMT630A emulator with 320x240 pixel TFT video, and standard 3KEY keypad input, allowing to create/debug AMT630A software...

The XED Editor (separately required for DOS version only)
The no$x51 built-in source code assembler is parts of able to communicate with my XED editor (download here). That is, access the editor by hitting ALT+E from inside of no$x51, edit your source code, hit F9 in the editor, this will assemble your program and, if no errors occured, autostart it in the emulator, otherwise, in case of assembly errors it'll switch back to the editor, and automatically move it to the first error-line.
Installation notes: Copy XED into a directory which is part of your PATH (eg. your C:\Windows directory, if you are using windows), and select XED as preferred editor in no$x51 setup!
